What is the place value of the digit 4 in the number 5,140,687? => thousands or hundreds or ten thousands or tens..

Approximation - We know that the digits of a number, one by one in order from left to right decrease in value rapidly. Let us illustrate it by examples. Mass of a gold ornament is 23.473 g. Round off to (i) two decimal places, (ii) one decimal place..

Introduction - We use specific number of digits to denote an exact value of a number for required accuracy. The digits used for such a purpose are called significant figures. Suppose a measurement is recorded as 0.6204 cm. It means that the measurem..

We use specific number of digits to denote the value of a number to a certain degree of accuracy. For a number between 0 and 1, the successive zeros after the decimal are not significant. For a number with a decimal point, the fina..

Question: Using the given values of a and d find the first five terms of A.P. and the general term. a = 4, d = 3 Answer: The first five terms are: ..

Let p(x) = 5x 2 +6x-8 Factors of the constant '8' are 1,-1,2,-2,4, -4 and 8,-8. Let us find the value of p(x) at each one of them to get one factor. p(-2) = 20-12-8 = 0 Divide 5x 2 +6x-8 by x+2 to get the other factor. ..

Working rules for expanding (a + b) n n N: Step 1: The value of index, n implies that there will be n+1 terms in the expansion of (a + b) n . Step 2: Write the first term: n C 0 a n b 0 . Step 3: For the second term, take coefficient as n C 1 , decrea..

>A system of linear equations is said to be consistent if it has at least are solution, otherwise it is inconsistent. Let A be asquare matrix of order n. Following are the steps to find the inverse of a matrix. Step 1: Find the value of the determinants A. That is, find |A| Step 2: If |A|..

Question: Find the first four terms of the sequence 4 + 5n. Which term of the sequence is 99? Answer: When n = 1, t 1 = 4+5(1) = 9. When n = 2, t 2 = 4+5(2) = 14 When n = 3, t 3 = 4+5(3) = 19. When n = 4, t ..

Question: For given sequence, find the first four terms. Answer: ..
